Research On Characteristics Of High-intensity Running Of Chinese Football Association Super League Team

Using big data to carry out scientific statistical analysis of modern football,trying to find out the characteristics and regularity of players' running characteristics in football matches,aiming at seeking more space for the development of football in China.Physical fitness is the most basic condition in football competition.Paying attention to the physical training of football players and improving the running ability of football players is the common understanding of the world football.It is the main purpose to correctly understand and master the rules of football and improve the ability of competition.The research object of this paper is the running data of 18 teams in the Super League team.The total number of games is 480,and the time span is 23 in the two seasons from2015 to 2016.This study uses the speed standard set by UEFA to statistically analyze the high-intensity running distance and time interval of the 18 teams of the China Football Super League League in order to gain an in-depth understanding of the high-intensity running of the Super League team.Develop training plans for each team,arrange training support to provide theoretical support,and ensure the scientific training of the team.1.Research method: Through the total of 23 indicators of the team's 18 teams in the two seasons of 2015-2016,the statistics of each team's running data are clustered,T-value test and CART are used.The decision tree is modeled and analyzed to perform regression testing on the results.2.Results:1.The cluster analysis method can objectively distinguish the types of teams in the Super League.When the team's three indicators take values ??at 5200 ?(sprint distance,high-strength running distance,high-speed running distance)? 4379;the team is returned Class to the first type of team;conversely;when the team's index value is 4490 ?(sprint distance,high-strength running distance,high-speed running distance)? 4847,the team is classified into the second type of team.2.T-test of the total distance traveled by the two types of teams,the distance of sprinting,the total distance of high-speed running,the number of sprints,the number ofhigh-speed running,the number of high-intensity running,and the high-intensity running distance in different time periods.P value> 0.05,indicating that there is no significant difference;the two groups of teams run the total distance when the ball is controlled by the party,and the P value of the total distance of the opponent's running ball is <0.05,indicating that there is a significant difference.3.There is no significant difference in the overall high-intensity running between the two teams in the game and in the second half,but in the three stages of the game 0-15 minutes,45-60 minutes,75-90 minutes,high-intensity running characteristics There are significant differences.4.The two types of teams are roughly equal in the number of high-speed running times and sprints.The first-class teams have higher-intensity running times than the second-class teams and the first-class teams.The second type of team.3.Conclusion1.In the Super League,the strong team's running ability on both ends of the offense and defense is relatively balanced.The stable performance of the physical team lays the foundation for the team to win.The strong team wins the anaerobic metabolism.In the weak team,the weak team is slightly higher than the strong team in aerobic metabolic metabolism.2.In the Super League,the strong team's high-intensity running in the first half and the descending arc are basically the same as the weak team.After the start of the second half,the weak team's high-intensity running is more prominent than the strong team;in football In the game,the most goals are only in the second half of the second half.The serious lack of physical fitness may be the main reason for the weak team's serious shortage in the standings.3.In the Super League,15 minutes after the start of the game,compared with 15 minutes before the end of the game,the high-strength running of the strong team and the weak team 15 minutes after the game showed a downward trend with a similar range,about 18%-20%.4.In the Super League,the ability of a strong team to complete a high-intensity run is stronger than that of a weak team,and the ability of a strong team to continuously withstand high-intensity is also stronger.
